Sunless Citadel

The ancient edifice, now called the Sunless Citadel, was once the redoubt of the Vampire Lord Gulthias Sengir until the vampire was staked by a cursed spear to the Gulthias Tree by his forgemaster Hector.

Our Heroes conscripted many of the inhabitants of the Citadel in their efforts to thwart Belek, but in the end the undead dragonpriest Miraak gained rulership of the Citadel instead. The Gulthias Tree, at least, has been destroyed.
